Collection and habitat data
Little was previously known about the habitat associations of this rare species. One specimen from Quebec was collected from large gilled mushrooms on the side of a log (Campbell 1982[1]). Four specimens of this species were collected from Pleurotus sp. mushrooms on the side of Populus logs in a hardwood forest in Saint-Raphaël (15.VII.2006), Quebec (Webster, unpublished). Most specimens from New Brunswick were collected from Pleurotus sp. mushrooms on standing dead Populus sp. trees or on the side of logs in mature hardwood forests with sugar maple and beech. Some adults were also collected from a large orange-gilled mushroom on the side of a log. One individual was collected from inside a Laetiporus sulphureus (Fr.) Murr. (Polyporaceae). These data suggest that this species may be specialized on Pleurotus sp. and other large gilled mushrooms that grow on standing dead trees or logs. Campbell (1982)[1] suggested that this species, like Lordithon niger and the European Lordithon bicolor (Gravenhorst), may be associated with old-growth hardwood forests. Adults of Lordithon axillaris were collected during June, July, and August in New Brunswick.
